Abstract

CIRCUITO DE CONTROL DE CONTINUA EN RECEPTORES DE DATOS A RAFAGAS. DEL TIPO DE LOS QUE REALIZAN UN DESACOPLO DE CONTINUA MEDIANTE CONDENSADOR, PARA AISLAR EL RECEPTOR DE ENTRADA DE ETAPAS POSTERIORES. APLICABLE EN SISTEMAS DE TRANSMISION DIGITAL A RAFAGAS POR FIBRA OPTICA EN BUCLES DE ABONADO. EL CIRCUITO DE LA INVENCION COMPRENDE UN RECEPTOR DE LINEA (1) QUE CONVIERTE LA SEÑAL RECIBIDA POR UN MEDIO DE TRANSMISION EN UNA SEÑAL ELECTRICA (S), UN CIRCUITO DE DESACOPLO DE CONTINUA (C, R1) Y UN PRIMER AMPLIFICADOR (A1). SE CARACTERIZA PORQUE COMPRENDE ADEMAS UN CIRCUITO DE CONTROL (2) QUE MIDE LA COMPONENTE CONTINUA EN EL NODO DE ENTRADA DEL PRIMER AMPLIFICADOR (A1) DURANTE LOS INSTANTES DE LA TRAMA EN LOS QUE NO SE RECIBE SEÑAL, Y UN GENERADOR DE CORRIENTE (I) QUE ENTREGA A DICHO NODO UNA CORRIENTE CUYO VALOR ES DETERMINADO POR EL CIRCUITO DE CONTROL (2), DE FORMA QUE COMPENSEN EL INCREMENTO DE TENSION PRODUCIDO EN EL CONDENSADOR DE DESACOPLO.CONTINUOUS CONTROL CIRCUIT IN DATA RECEPTORS TO GUSTS. OF THE TYPE OF THOSE WHO PERFORM A CONTINUOUS DISCONNECTION BY CONDENSER, TO ISOLATE THE RECEIVER OF ENTRY FROM SUBSEQUENT STAGES. APPLICABLE IN DIGITAL TRANSMISSION SYSTEMS TO GUSTS BY OPTICAL FIBER IN SUBSCRIBER LOOPES. THE CIRCUIT OF THE INVENTION INCLUDES A LINE RECEIVER (1) THAT CONVERTS THE SIGNAL RECEIVED BY A TRANSMISSION MEANS INTO AN ELECTRICAL SIGNAL (S), A CONTINUOUS DISCONNECT CIRCUIT (C, R1) AND A FIRST AMPLIFIER (A1). IT IS CHARACTERIZED BECAUSE IT ALSO INCLUDES A CONTROL CIRCUIT (2) THAT MEASURES THE CONTINUOUS COMPONENT AT THE ENTRY NODE OF THE FIRST AMPLIFIER (A1) DURING THE INSTANCES OF THE FRAME IN WHICH NO SIGNAL IS RECEIVED, AND A CURRENT GENERATOR (I) THAT DELIVERES TO SUCH A NODE A CURRENT WHOSE VALUE IS DETERMINED BY THE CONTROL CIRCUIT (2), SO THAT THEY INCREASE THE VOLTAGE INCREASE PRODUCED IN THE DISCONNECTION CAPACITOR.
